C++: meaning of std::ostringstream& var

Question

I want to implement a function with a parameter that will receive a string result:

bool function (entry parameter, std::ostringstream & var)

I'm not sure about what it is, pointer ?

Should I do something special about it or just: var << result ?

The return value is boolean but we will need var after

& means it is a reference, not a pointer. See Andrew's comment link. You do not need to delete var, if that is what you mean by "something special." Given the method signature you provided, the code:

var << result;

should work just fine, assuming "result" is something sane. If you need more information, you may need to post a MCVE.
